One Sunday morning, I wanted to buy a computer to use for school.  I went to the(big) store in town, which sold all kinds of computers. There were many computers there that I didn't know" how to choose a right one. Then a young man greeted me with a sweet smile. He looked like not a salesman a student like me .I had a strange feeling as if I had met him before.  He began showing me each model (patient). With his help, I decided (buy) one computer with enough functions at a very low price. I enjoyed this shopping experience because of his smile. A few (month) later, something was wrong with my computer. I went back to the store to have it repaired. When I arrived there, what I saw was still his smile. As soon as I told him my problem, he comforted me immediately and tried his best to (solve) the problem for me. I was quite thankful for (he) sweet smile and good service.

    When I went back to school, his smile often appeared in my mind. I realized smiling is most peaceful language in the daily life. I don't know  we'll meet each other again, but his sweet smile will stay there in my memory and deep in my heart.
